SummaryThe puma (Felis concolor) has the most extensive range of any terrestrial mammal in the Western Hemisphere, covering over 100° latitude. Food habits of different puma subspecies vary with latitude. Subspecies from temperate habitats generally eat larger prey and specialize on a smaller number of prey taxa, whereas, in tropical habitats, they prey on smaller, more varied prey. In North America, ungulates (primarily deer) represented 68% of the puma's diet by frequency of occurrence. Mean… 
Food Niche of Puma concolor in Central Mexico
It is concluded that the nine-banded armadillo Dasypus novemcinctus is the main prey, followed by the white-nosed coati Nasua narica and white-tailed deer Odocoileus virginianus, and the puma's standardised niche breadth was 0.21 and was in accordance with the expected in the exponential model.
Food habits of sympatric jaguars and pumas across a gradient of human disturbance
It is suggested that jaguar predation on cattle may be reduced by ensuring that game hunting is sustainable and potentially by augmenting forests within the human matrix with large wild ungulates.
Food Habits of Jaguar and Puma in a Protected Area and Adjacent Fragmented Landscape of Northeastern Mexico
The diet of both felids included almost exclusively wild species, suggesting the presence of a good prey base that allows the coexistence of jaguars and pumas in a protected area surrounded by a fragmented landscape in northeastern Mexico.
Diet of Puma (Puma concolor, Carnivora: Felidae) in Coastal and Andean Ranges of Southern Chile
In order to maintain viable populations of pumas in the biologically most interesting coastal forests, it will be necessary to protect larger native forests that provide enough food and habitat for pumAs.
Feeding ecology of puma Puma concolor in Mexican montane forests with comments about jaguar Panthera onca
Analysis of puma scats showed that their main prey was nine-banded armadillo Dasypus novemcinctus followed by white-nosed coati Nasua narica and white-tailed deer Odocoileus virginianus, which formed the bulk of their diet.
Habitat diversity influences puma Puma concolor diet in the Chihuahuan Desert
Habitat heterogeneity and corresponding diversity in potential prey species should increase the diet breadth of generalist predators. Many previous studies describing puma Puma concolor diets in the
Trophic interactions between puma and endemic culpeo fox after livestock removal in the high mountains of central Argentina
Native prey are the most important food items for both carnivores inside the park; these results are encouraging in terms of the resilience of at least some components of the predator-prey assemblage in the high mountains of central Argentina.
Response of pumas (Puma concolor) to migration of their primary prey in Patagonia
The response of pumas to the migration of guanacos differs from sites in the western North America where entire prey populations migrate and pumaas migrate with their prey or switch to more abundant prey when their primary prey migrates.
Biogeographic patterns in the feeding habits of the opportunist and semiaquatic Neotropical otter
Neotropical otter diet was found to be more similar in geographically closer areas, as well as in similar environment types, and this plasticity might be explained by the wide range of habitats occupied by otters.


Feeding ecology of the Patagonia puma in southermost Chile
The feeding ecology of the Patagonia puma (Felis concolor patagonica) was studied in Torres del Paine National Park, Chile, by analyzing seasonal and yearly variation in 590 prey items found in 405

Analysis of scats showed terrestrial mammals to be the chief prey of all three felids, but reptiles and birds were also numerically important in the diets of ocelot and jaguar.
Food habits of panthers in southwest Florida
The diet of Florida panthers in southwest Florida from 1977 through 1989 was examined and wild hog was the most common prey followed by white-tailed deer, raccoon, and 9-banded armadillo; however, panthers inhabiting an area of better soils consumed more large prey.
Cougar food habits in southern Utah
Diets of cougars were studied from December 1978 to August 1981, on a 4,500km2 study area near Escalante, Utah, and it was determined that the number of "field-collectible" scats produced by gray wolves (Canis lupus) was inversely related to prey size.
Food habits of the southernmost mountain lions (Felis concolor) in South America: natural versus livestocked ranges
Little is known about the ecology of South American mountain lions (Currier, 1983; Schaller and Crawshaw, 1980; Schaller, 1983). Even in Chile, perhaps the best known country mammalogically in South
Carnivore body size: Ecological and taxonomic correlates
Variation in body size (weight) is examined across the order Carnivora in relation to taxonomy, latitude, habitat, zonation, activity cycle, diet, prey size, and prey diversity and the adaptive significance of prey characteristics and carnivore body weight qualities is discussed.
Mammals and their biomass on a Brazilian ranch
An analysis of food habits revealed several trends in resource use: terrestrial mixed browsers and grazers - tapir and deer - contributed most to the biomass; primary grazers were absent, except for the semi-aquatic capybara; and arboreal folivores were rare, comprising only howler monkey and porcupine, with 3% of the total biomass.
On the Ecological Separation between Tigers and Leopards
Coexistence in Chitawan is facilitated by a large prey biomass, a larger proportion of the ungulate biomass in the small size classes, and by the dense vegetation structure, and some consequences of predator size and the role of interspecific dominance are discussed.
It is demonstrated that weasel differ in their degree of specialization on mouse-sized food, larger weasels taking a greater size variety, which is possibly a coexistence-stabilizing force.
Geographic variation in size and sexual dimorphism of North American weasels
Latitude is a better predictor of size in erminea than available measures of climate, seasonality or prey size, and regional differences in the abundance of prey during the growth of young weasels may affect adult size much more in males than in females and contribute to geographic variation in sexual dimorphism.
